A new paper published May 15th in the the journal The Cryosphereutilizes 12 years worth of RADARSAT data to determine the rate at which some well known ice shelves in Antarctica have been moving and changing, and the answer is: not much. In fact it appears there has been a slowing down. First a map of Antarctica and the most worrisome Ross Ice Shelf (marked by the red x) is in order:

If you follow the alarmosphere and MSM related to the Ross Ice Shelf and others, you get these kinds of stories:

The expansion of the polar air masses whilst the sun reduced its activity levels after the peak of cycle 23 resulted in a relaxation of the westerly air flow around Antarctica which had previously been skimming ice away from the edges especially on the Antarctic Peninsula which projects out into those winds.

Zonal jetstreams show an enhanced and tighter such air flow around Antarctica and zonal jets are associated with high levels of solar activity on multidecadal and centennial timescales.

This report is further evidence that a climate regime change occurred around 2000 which was when I first noted that the poleward drift of the jets and the permanent climate zones had apparently ceased.

Since 2000 the jets and climate zones have begun an equatorward drift and in due course the effect on ocean heat content will become incontrovertible (unless the sun perks up again).

17 May: iTWire: David Heath: Its official  climate change is human-caused Having exhausted all other possible causes, Melbourne University researchers conclude that the dramatic increase in local temperatures over the past 60 years can only be human-caused. A team of over 30 paleoclimatologists has spent the past decade examining natural records of climate including recent geologically preserved sites along with written records (eg newspapers) and other data (corals, tree rings and Antarctic ice cores amongst many others) to construct a detailed view of climate changes in the Australasian region over the past 1000 years. Lead researcher, Dr Joelle Gergis from the University of Melbourne saidsaid the results show that there are no other warm periods in the last 1000 years that match the warming experienced in Australasia since 1950. This period far exceeded the magnitude of warning in the so-called Medieval Warming period of 1238  1267 According to the research team, the climate reconstruction was developed using 27 natural climate records calculated in 3000 different ways to ensure the robustness of the conclusions A PDF of the paper published in the Journal of Climate is available here for a fee. The research will form the regions submission to the 5th IPCC climate change assessment report chapter on past climate due to be published toward the end of 2014.http://www.itwire.com/science-news/climate/54765-its-official-climate-change-is-human-caused

UK Guardian & other MSM already jumping on this one.

When discussing the effects of the Antarctic ice melt, it is often overlooked that some part of Antarctic ice is floating ice and not continental ice, and further that the ice shelfs that are presently and/or most prone to calving are already floating and therefore will not add to sea level rise.

Call me stupid if you wish but isnt the Ross Ice shelf already floating in the sea? If so, how will it raise sea level when it breaks away? _____________________________ This is not about science it is about scaring the chicken littles into jumping off a cliff.
